The Relativistic Transformation to Rotating Frames [PDF]

NuovoCim.B115:307-318,2000, 1999
We present a critical review of the relativistic rotation transformation of Trocheris and Takeno. A new transformation is proposed which is free from the drawbacks of the former. Some applications are presented.

A derivation of coincidence relations utilizing quaternion and matrix based on the hexagonal lattice for material engineers

International Journal of Mathematics for Industry, 2019
Grain-oriented silicon steel is mainly used as the core material of transformers, and it is manufactured by applying secondary recrystallization. The driving force of this process is the grain boundary energy, based on the nature of the grain boundary ...

Visual Form Perception Can Be a Cognitive Correlate of Lower Level Math Categories for Teenagers

Frontiers in Psychology, 2017
Numerous studies have assessed the cognitive correlates of performance in mathematics, but little research has been conducted to systematically examine the relations between visual perception as the starting point of visuospatial processing and typical ...

Clinical and functional outcomes of reverse total shoulder arthroplasty supplemented with latissimus dorsi transfer: a systematic review and meta-analysis

JSES Reviews, Reports, and Techniques, 2023
Background: To optimize patients' functional external rotation outcomes, reverse total shoulder arthroplasties (rTSAs) including a latissimus dorsi tendon transfer were undertaken with promising early results and no significant increase in complications ...

Generalizing the MOND description of rotation curves [PDF]

arXiv, 2001
We present new mathematical alternatives for explaining rotation curves of spiral galaxies in the MOND context. For given total masses, it is shown that various mathematical alternatives to MOND, while predicting flat rotation curves for large galactic radii, predict curves with different peculiar features for smaller radii.

A Wick-rotatable metric is purely electric [PDF]

arXiv, 2015
We show that a metric of arbitrary dimension and signature which allows for a standard Wick-rotation to a Riemannian metric necessarily has a purely electric Riemann and Weyl tensor.
